Central line associated bloodstream infection in general surgery patients

Abstract

[eng] BACKGROUND: The aim of this study was to determine the incidence and the factors in uencing the positivity of central line associated blood- stream infection (CLaBSi) in No intensive Care unit (no-iCu) patients and its relation to the use of total parenteral nutrition (TPN), taking as sample patients of the department of general surgery. METhODS: Data were collected on a prospective observational study. Patients requiring a central venous catheter for TPN during their stay in the department of general surgery between april 2014 and July 2015 were analyzed. it was studied the occurrence of a CLaBSi and analyzed the characteristics associated with it. The variables taken into consideration were age, nutritional anthropometric and biochemical parameters, admission diagnosis, duration of hospitalization, inpatient surgery section, the usage of antibiotic therapy through the catheter, location of CVC and microorganism isolated in cultures. rESuLTS: One hundred and twenty-nine patients were included and one hundred forty-eight catheters were placed. The cumulative incidence of CLABSI was 16.28%. The comparison between the patients who presented CLABSI and those who had not show signi cant differences in the duration of the infusion of TPN (P=0.005) and in the time of the central venous catheter (P=0.02). The median survival of free for CLaBSi catheter was 41 days (Ci-95%: 21.2-55.4). CONCLuSiONS: as the literature describes the TPN is an independent unfavourable factor. Catheter infection due to the TPN is an eventuality to be considered, especially in surgical patients, who often require parenteral nutrition as a way of feeding. Preventing a CLaBSi may prevent situations that complicate the stay of surgical patients.
